CARBURETER.

Specification of Letters Patent.

Patented Fenu, 1919.

Application led January 7, 1918. Serial No. 210,658.

To all whom t may concern Be 'it known that I, ANTHONY J. PICHL, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Carbureters, of which the following is a full, clear, 'i

"by suction from the spray nozzle of the carbureter, and which passes in vapor form to the combustion chamber of the engine.

The principal object of my invention is to provide simple and eilicient means whereby the flow of volatile fuel which forms the basis of combustion in the engine cylinder nay be very accurately controlled and reguated.

A further object of my invention is to provide regulating means preferably in the form of a valve which operates entirely independentof the valve whichv controls the flow of air to the carbureter and also independent of the valve which controls the flow of liquid hydrocarbon from the v.source of supply to said carbureter.

Another object of my invention is to associate with my improved valve, suitable operating connections, the latter capable of being actuated from a point a considerable distance away from the carbureter, for instance, on the steering post near the steering wheel, or from the dash. of the vehicle having a carbureter equipped with my improved gasolene control valve.

With the foregoing and other objects in View, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is an elevational view of a portion of a carbureter and a portion of a motor vehicle steering post and showing my invention applied thereto.

Fig. 2 is a vertlcal section through the lower portion of a carbureter and showing my improved gasolene control valve associated therewith.

Fig. 3 is an elevational view of the valv detached from the carbureter.

Fig. 4: is an enlarged detail sectional view of the upper end of the gasolene discharge nozzle within the carbureter and showing the valve which is associated with said nozzle in full open position.

Fig. 5 is a plan view of an operating lever for my improved valve and whichvlever is adapted to be positioned on the steering post of a vehicle.

Fig. 6 is a sectional view of a clamp which is adapted to be applied to the steering post and upon which the operating lever for the valve is mounted.

Referring by'numerals to the accompanying drawings which illustrate a practical embodiment of'my invention, 10 designates the lower part of a carbureter of ordinary construction -and operating therein is the usual float 11 which actuates a valve (not shown) and which latter controls the admission of liquid hydrocarbon or gasolene to the chamber 12 within member 10.

Centrally arranged within member 10 is a member 13 provided with a nozzle chamber 14 and seated in the vbottom of said member 13 and projecting upwardly into 'said chamber 14 is a tubular nozzle 15, the

upper end thereof being provided with a tapered jet or spray opening 16. Ports 17 establish communication between the lower portion of chamber 12 with the opening or passageway through nozzle 15. It will be understood that the parts just described are of ordinary and Well-known construction.

The valve contemplated by my invention includes a rod 18, the upper end of which is tapered as designated by 19 and of such size as to lit snugly in the tapered jet or spray opening 16. This rod is arranged to slide freely through a suitable cylindrical member 20, the upper portion 21 of which is externally threaded and seated in a depending portion 22 of the carbureter body 10. Screw-seated in the lower portion of the cylindrical body 20 is a gland-or packing nut 23 through which the lower portion of rod 18 slides freely. Formed integral with or fixed to the lower portion of the body 20 and depending from one side thereof is a short bracket 24, the same servingvas a bearing fora short horizontally disposed shaft 25.

Formed on one end of this shaft is a comparatively short crank 26 and Journaled therein is a laterally bent lower end 27; of rod 18.

Secured in any suitable manner to the end of shaft 25 opposite the end provided with the crank 26 is a short crank arm 28 to the lower end of which is pivotally connected one end of an operating rod 29. This rod can `be extended to any convenient point remote from the carbureter, but where the carbureter equipped with my improved valve 1s utilized in connection with the internal combustion engine of a motor vehicle, I prefer to extend said rod along the steering column of the vehicle. This rod is necessarily. exible to a certain degree and where it is extended along the steering column, I prefer to inclose it in a housing, such as a small tube 30, the

latter being secured to the column in any suitable manner.

As a convenient means for shifting the rod 29 lengthwise to regulate the position of the valve, I prefer to connect the upper end of said rod to a short operating lever such as 31, the same lbeing pivotally connected to a' bracket 32 which is located on the steering column vadjacent tothe wheel at the'up er end thereof. If desired, a portion of t isv per end 19 o f rod 1 8 fits snugly in the `tapered jet or spray opening 16, las shown in4 Fig. 2, and when the Valve is in/its full open position, rod 18 and tapered end 19A occupies .the position shown in Fig. 4.

As illustrated in Figs. 2 and 4, the normal gasolene level is in a' plane slightly below the extreme Aupper end of nozzle 15, and when rod 18 is drawn downward to partially open or unseat the valve, s'. yproportionate yamount of liquid gasolene "will be drawn upwardly through the tapered opening 16 on each intake or suction gine. y By proper manipulation of the lever 31, my improved valve can be easily and quickly stroke of the enshifted to any intermediate position-between full open and full closed, thereby e'ectmg a positive and accurate regulation and control of the amount of volume of gasolene passing from the nozzle of the carbureter into the mixing and vaporizing chamber thereof, and fromI the latterv to the cylinders of the engine, this regulation, of course, ,being dependent on the conditions under which the engine is operating and accomplished by the operator from his seat in the vehicle..

The particular form of device herein illustrated and described is particularly intended for use in connection with a number of carbureters now manufactured and on the market, and it can 1be readily applied to these carbureters without change in their structure.

It will be understood that no limitation is necessarily made to the precise structural details herein disclosed, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

I claim:

A1. The combination with a carbureter having a jet nozzle through ,which liquid hydrocarbon is adapted to pass, of a tubular member seated in the carbureter, a valve' member mounted for reciprocating movement in said tubular member, the inne-r end of which valvel member is adapted to close the passageway through the jet nozzle, a bell crank mounted for operation on the outer portion of said tubular member, one'arm of which bell crank is connected to the reciprocating.

valve member, bell crank.

2. The combination with a carbureter having a jet nozzle through which liquid hydrocarbon is adapted to pass, of a tubular memand means for actuating said ber seated inthe carbureter, a valve member mounted for reciprocating movement in said 'tubular member, the inner end of which valve member is adapted to 'close the passageway through the jet nozzle, abell crank mounted for ,operation on the outer portion of said tubularmember, one arm-of which bell crank is connected to the reciprocating valve member, a rod connected to the other arm of the bell crank,'which rod extends a substantial distance away from the carbureter and an operating llever connected to said rod.

In testimonywhereof I hereunto afx my signature this 28th day of December, 1917. ANTHONY PICHL.
